DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1022 AM CST WED NOV 28 2007
VALID 281630Z - 291200Z
..NO TSTM AREAS FORECAST...
..SYNOPSIS...
BROAD CYCLONIC FLOW WITH EMBEDDED FAST-MOVING SHORTWAVE TROUGHS WILL
PERSIST FOR THE NEXT FEW DAYS ACROSS THE NRN HALF OF THE CONUS. A
RELATIVELY COOL/STABLE CONTINENTAL AIR MASS COVERS THE MAJORITY OF
THE CONUS TO THE N OF CENTRAL FL...WHILE RICHER MOISTURE /68-70 F
BOUNDARY LAYER DEWPOINTS/ IS PRESENT S OF A WEAKENING FRONT ACROSS
CENTRAL FL. HOWEVER...12Z SOUNDINGS CONTINUE TO SHOW POOR LAPSE
RATES AND RATHER WEAK INSTABILITY OVER CENTRAL/S FL. WATER VAPOR
IMAGERY SHOWS A WEAK MID LEVEL TROUGH ALREADY MOVING OVER/E OF N
FL...AND THERE WILL BE LITTLE TO FOCUS THUNDERSTORM DEVELOPMENT THIS
AFTERNOON OTHER THAN SUBTLE DIURNAL PROCESSES. AN ISOLATED STRIKE
OR TWO CANNOT BE RULED OUT TODAY NEAR THE FRONT ALONG THE FL E
COAST...AND ACROSS INTERIOR SE FL...BUT THE OVERALL THREAT STILL
APPEARS TOO MARGINAL TO WARRANT ADDITION OF AN OUTLOOK AREA.
